On each and every day several times we have to open and close doors, half-doors and like-wise at home, office, railway stations, airports, hotels, parks etc. etc. Most of these doors and half-doors are automatized, especially in air-conditioned rooms. Many of us close the door immediately after we enter, without looking back whether somebody is coming behind us, resulting in much inconvenience to them, sometimes the door banging on their face. When opening the door also, this problem may arise if somebody is on the other side.
What is to be done? Kindly look back before you close the door to find out whether anybody is following you. In that case, hold the door, half-door till the other person hold the same. This is only but courtesy and good manners. It will be much appreciated.
